You probably did not get the drum unit seated in place and the drum is not grounded. Make sure your lamp is coming of the charge wires is not all the way in. Go back and reseat the drum unit. Check it twice. And you did release the developer. I hope so. If not that's what keeping this unit from being in the correct position.

SOURCE: Minolta 2300DL Printer - black streaks

Hey Chuck, Any chance you can post a scan of one of the faulty pages ? This will make it easier to assess the fault. Print off about 10 pages of a page that is affected by the lines. Look at each page and see if you can detect a recurring pattern over any of the pages. If there is a pattern, chances are it is probably the PCU that is marked.

Yes Cartridge problem is what causes double imaging 95 % of the time, there is a rubber blade in the drum unit that wears and doesn't clean off old image from drum. Have known this fault to be fuser at times, the way to tell is to get a print to stop half way threw machine by openning door during print, remove cartridge and look at print, you want it to be stop before the fuser(hot bit) but after the drum, image still rubs off if pre fuser and then you can see if defect is present before paper travels threw the fuser, but in your case I think you will find it is not the fuser it is toner cartridge.

In my ir3300 xerox in very light if any setting is there make to dark print?.... what is the setting can u help me ?plz

Check your drum. if drum is ok clean the laser unit and clean the drum unit and chraging roller.
And clean the laser scanner lamp and the Mirror.
You must alert while cleaning the mirrors(Reflectors) don't use thinner, alcohol and stain removers for cleaning scanner lamp and mirror don't do that to movements the reflectors just open the copy board glass and clean with a cotton.

Does not print black even though cartridge is full and ink seemingly flows out of the cartridge when touched with a paper towel. All other colors work OK

You have followed the first fault find step correctly these are the next steps :

1) A poor contact exists in the developing bias contacts of the
high-voltage PCB and the print cartridge.
Clean the contacts. If they are still dirty after cleaning, or if
they are damaged, replace the print cartridge or the highvoltage
contacts. Replace the high-voltage PCB.

2) The laser/scanner unit is defective. Replace the laser/scanner for the missing color. Calibrate the printer after
replacing the laser/scanner.

3) The high-voltage PCB is defective or one of the connections
is loose.
1. Check the connections.
2. Replace the high-voltage PCB.

4) The DC controller PCB is defective or the connector to the
high-voltage PCB (J1006) is disconnected or not seated
1. Upgrade the DC controller PCB firmware.
2. Check the connector (J1006) on the DC controller PCB
to make sure it is seated correctly.
3. Replace the DC controller PCB.
Calibrate the printer after replacing the
DC controller
Hope that helps........

The machine is full black when I do photocopy using a feeder(ADF) or using a glass.When I print a maintenance report using 1087 2 times then the printing is very clear.

if you can print fine and it is just when you copy from the adf or the glass then check the mirror and carriage alignment, the ccd, and the lamp. sometimes the lamp is visible but is too weak to do its job. if you replaced the drum and lsu while it still generated internal prints okay you wasted time and money.... but anyway. if you replaced the ccd and the mirrors and lamps are okay then it sounds like the board.

Canon photocopier iR2016 displaying "waste toner full" on screen. How do I fix this?

Hi there you can empty the waste toner box wich is located inside drum unit.

The procedure is next:

open front cover and leftsideway door
release the blue handle above the drum unit
pull out the drum unit
on top of drum unit, near handle is located plastic grey colored cork
remove it and by means of vacume cleaner clean the vaste toner.

Note that if you flip out the drum unit and try to empty waste toner it could be messy and the toner can get into charge roller or on drum cleaning blade and then you need to change it completly.

hope that hepls

Black dots printing on left side of paper

dots are usually always caused by the drum..drums are very easy to replace..(you don't even need a screwdriver)
here's how..
remove the unit that the toner sits's called a process unit..comes out as a whole with the toners...
next open left cover..
remove waste toner bottle. (drum sits right above it!!!
next remove drum by pushing on grey button and pulling drum
out the left side of the printer.

as far as the jam message you might need to replace tray feed tires located up under the machine

Black lines on copies

Have you cleaned the optical path and the laser cover glass? Remove the glass and clean all the mirrors with a soft lint free cloth. Do not use and sprays or cleaners, just a dry cloth. Clean the scanner bed and the glass for the ADF if it has one.
